Abstract Scope |
The influence of Al content(0.5,0.7,and 0.8) on hot ductility of high-strengh steel was studied by experimental hot tensile tests in the temperature range of 600-1300 °C and strain rate of 0.001 s-1 on a Gleeble-1500 thermal simulation machine. The true stress-strain curve was obtained and the reduction of area was calculated.The results show that when the Al content is 0.5%, the reduction of area is less than 40% at 600-1000 °C; when the Al content is 0.7%, the result is close to the Al content of 0.5%; when the Al content is 0.8%, the reduction of area is less than 40% at 650°C-1050°C.In addition, the fracture morphology of the sample was observed by SEM, and fine precipitates were found at the fracture. At the same time, the structure near the fracture was observed under an optical microscope and the grain size was counted. |
